Acquired intravesical ureteral diverticulum: an unusual late complication of ureteroneocystostomy.

An unusual case of late ureteral obstruction following a Politano-Leadbetter ureteroneocystostomy performed 11 years previously is reported. Fibrosis of the distal ureter associated with vascular compression of the extravesical ureter presumably led to development of a ureteral intramural diverticulum. This case illustrates the necessity of careful ureteral placement and emphasizes the importance of close followup for many years, even in asymptomatic patients.
